Stecformer: Spatio-temporal Encoding Cascaded Transformer for Multivariate Long-term Time Series Forecasting

no code implementations25 May 2023 Zheng Sun, Yi Wei, Wenxiao Jia, Long Yu

With the development of transformer-based methods, the performance of multivariate long-term time series forecasting has been significantly improved, however, the study of spatial features extracting in transformer-based model is rare and the consistency of different prediction periods is unsatisfactory due to the large span.

A General 3D Non-Stationary Massive MIMO GBSM for 6G Communication Systems

no code implementations17 Jan 2021 Yi Zheng, Long Yu, Runruo Yang, Cheng-Xiang Wang

A general three-dimensional (3D) non-stationary massive multiple-input multiple-output (MIMO) geometry-based stochastic model (GBSM) for the sixth generation (6G) communication systems is proposed in the paper.

DT-Net: A novel network based on multi-directional integrated convolution and threshold convolution

no code implementations26 Sep 2020 Hongfeng You, Long Yu, Shengwei Tian, Xiang Ma, Yan Xing, Xiaojie Ma

To solve the above problems, in this paper, we propose a novel end-to-end semantic segmentation algorithm, DT-Net, and use two new convolution strategies to better achieve end-to-end semantic segmentation of medical images.

A New Multiple Max-pooling Integration Module and Cross Multiscale Deconvolution Network Based on Image Semantic Segmentation

no code implementations25 Mar 2020 Hongfeng You, Shengwei Tian, Long Yu, Xiang Ma, Yan Xing, Ning Xin

We use the output feature maps from the multiple max-pooling integration module as the input of the decoder network; the multiscale convolution of each submodule in the decoder network is cross-fused with the feature maps generated by the corresponding multiscale convolution in the encoder network.
